Linslade Tunnel

Linslade Tunnel is a railway tunnel in Bedfordshire, England (in an area that was historically in Buckinghamshire), on the West Coast Main Line about 0.54 miles (0.9 km) north of Leighton Buzzard railway station and built under Linslade Woods. Consisting of three individual bores, the tunnel is the only one on the London and Birmingham Railway to have been built on a bend. This was necessitated by the refusal of local landowners to allow the railway to pass closer to Leighton Buzzard, where the river has created a gap in the Bedfordshire Greensand Ridge. The first bore was constructed during the 1830s, the engineering of which having been performed by the pioneering railway builder George Stephenson. The only of the three bores to accommodate double track, it was first opened to traffic during 1837. During 1857, the eastern bore was added to serve the goods line from Bletchley to Primrose Hill and support a rebuild of Leighton Buzzard station incorporating a dedicated platform for the Dunstable branch line. Elsewhere on the line, goods trains shared the "up" track through twin-track tunnels. In 1876 a second freight line was added with twin-track tunnels except at Linslade, where a second single-track tunnel was added to the west of the original twin-track tunnel. A new pair of passenger lines was added at the west of Leighton Buzzard station and the tracks through the twin-tra
